Abstract: The present invention relates to a liquid leakage detector line for detecting the leakage, if occurs, of a liquid such as sulfuric acid or strong alkali from a transportion pipe line or a storage tank. The liquid leakage detector line comprises: a pair of wiry electrodes each including a conductor covered with an insulator layer made of macromolecular material including an ester bond, the wiry electrodes being disposed substantially in parallel with each other; and a liquid-absorbent material covering these wiry electrodes. The liquid-absorbent material may be a braided body layer made of liquid-absorbent yarn which is disposed outside of the pair of wiry electrodes, or may be a braided body layer similar to the first-mentioned braided body layer which is disposed at the outer periphery of each of the wiry electrodes. If a sulfuric acid or alkali liquid leaks, the liquid-absorbent material covering the wiry electrodes absorbs such leakage liquid.
